The next step in advancing the company's belief in the RFT paradigm is to advance the tire-makers' willingness to offer protocols for safe repair that even BMW's legal team would allow it's service departments to perform. And the tire dealers should offer repair services themselves. That multiple RFTs need to be purchased for a single tire's damage is becoming a rumor that could evolve into an annoyance if it should be true. BMW engineers may indeed be enabling this irritation to flourish. What a shame.
